You still need to start up a PostgreSQL database server and import the SQL scripts under:
/opt/Segs/Projects/CoX/Data
/opt/Segs/Projects/CoX/Servers/AdminServer/sql
/opt/Segs/Projects/CoX/Servers/GameServer/sql

Lastly, you need to set your address in /opt/Segs/out/local_1.cfg. If all goes well, you should be able to run ./authserver under /opt/Segs/out and connect to your new server with the client. In a future image, we'd like to have the PostgreSQL server up and ready to use.
